Conclusion

The LUMIX G VARIO 12-32mm F3.5-5.6 ASPH is a tiny and incredibly light standard zoom lens that's very much at home on the equally small DMC-GM1 camera. The build quality is surprisingly good, the OIS system effective, and it offers excellent image quality throughout the focal range when stopped down slightly from the maximum aperture. The only drawbacks for some will be the lack of a manual focus ring, making the user reliant on the very fast, silent and reliably accurate autofocusing system, something that most people certainly won't mind doing, and the rather slowish maximum apertures that are typical of a kit zoom lens, limiting its use in lower light. The LUMIX G VARIO 12-32mm F3.5-5.6 ASPH is still the perfect partner for the GM1 camera, though, and also a good investment in its own right if you want a versatile zoom that you can carry everywhere.
